Screw Conveyors Selection Points
Jun 22, 2017

Many customers want to use a screw conveyors, but do not know what type of screw conveyors to use, do not know how to choose the model. The following list describes the screw conveyors selection should pay attention to matters. Due to the different conveying materials, the main parameters are generally determined according to the requirements of the material handling system, the various premises of the material handling site, the relevant production process and the characteristics of the material.

Screw conveyors selection points

1, the transmission capacity: screw feeder capacity is the unit of time to transport the amount of material. In the transport of bulk material, the quality of the material delivered per hour or volume calculation; in the delivery of pieces of goods, the number of pieces per hour to calculate. When the vibrating screen equipment such as linear vibrating screen, rotary vibration screen and ultrasonic vibrating screen is matched, the feed volume of the vibrating screen is calculated and the conveying quantity is controlled. Most of the conveyors before the design and production should consider whether to use with other production equipment in order to facilitate the rational design of the conveyors model.

2, the transmission speed: progressive delivery speed can improve the transmission capacity. When the conveyors belt is used as a traction member and the conveying length is large, the conveying speed is gradually increased. But high-speed operation of the belt conveyors should pay attention to vibration, noise and start, brake and other issues. For conveyors with chains as traction parts, the conveying speed should not be too large to prevent the increase of the dynamic load. At the same time the process of handling the feeder, the transmission speed should be determined according to the production process requirements.

3, component size: conveyors component size, including conveyors belt width, lath width, hopper volume, pipe diameter and container size. These component sizes directly affect the conveyors capacity of the screw feeder.

4, the transmission length and inclination: the length of the transmission line and the size of the dip directly affect the total resistance of the conveyors and the required power. Now there are many types of conveyors, there are direct parallel feeding, and some with a certain tilt angle, so in the screw feeder selection to explain these conditions of use.

5, screw feeder motor can be used to adjust the speed of the motor and the general motor to control the transmission speed and the amount of delivery per hour.

6, in the feed port whether to add hopper, and the size of the hopper.
